To alt Iwhen?, it Imay concern: K

13e. it known that I, GUSTAV A. RAnowsKY, oif Duluth, St. Louis county,Minnesota, have invented certain new and useful Improvements inDumpCars, ot which the following is a speciiication. r

My invention relates to that type of dump car, designed particularly forhandling ore, receiving it at the mines and delivering it to the pocketsat the dock.

'lhc object of my invention is to simplify and improve the apparatusshown and described in 'Letters Patent of the United Sintes, No.899,682, issued to me September as, isos.

A further object is to provide a car, in which the load in the bucketswill be ltransmitted directly to the body holsters.

A. further object is to lprovide a system of bracing in the car frame,which will resist lateral and longitudinal strain.

The invention consists generally in an iinprovidcd car traine. e

Further,- the invention consists generally in improved uieans forlocking the buckets in their horizontal position.

Further, the invention consistsI in improved means :for tripping thelocking means.

Further, the invention consists in means for bracing the side framesagainst'. inward pull and distortion.

Further, the invention consists in various coi'istruetions andcombinations all as hereinafter described and particularly pointed outin the claims.

ln the accompanying drawings, forming part of this spociiioation, Figure1 is a. perspective view of a dumping far, embodying my invention,showing the buckets in their normal horizontal position, Fig. 2 is asinular view, illustrating the buckets in their dumping position, Fig. 3is a detail view, partially in section, illustrating the nieans forlooking the buckets in theirhorizontal position, and the mechanism fortripping the locking means, Fifi'. 4 is a similar view, showing thelocking mechanism in its releascd\or tripped position, Fig. 5 is adetail view oi one of the. locking latches.

ln the drawing, 2 represents a car frame, having trucks 3. Upon eachside of the car I iti-oxide lower side sills 4C composed preferably ofchannel bars, placed back to back I oi the car.

and riveted together. An arched ltrussy frame, forming the upper sidesills of the .ar is provided on .each side, as indicated by thereference numeral 5, and also coinposed of Vchannel bars placed back toback and riveted together. The upper portions of each side sill 5 isSubstantially horizontal above the middle portion ot the car and theends of the side sills are turned downwardly at a suitable angle andsecured to the car iframe andthe lower side sill, producing the desiredtruss etlect. Braces o of angle hars, having llanges placed back toback, are inserted between the horizontal portions oil the upper sidesills near the point where the angles are formed therein and their lowerends are secured above the body bolster in position to transmit theretothe load carried by said upper sills. Gusset plates 6 are interposedbetween the channel bars, co1nposing the sills 5 and the angle hars 6and securely riveted thereto, thus forming a rigid, substantialconstruction on each rlfransverse web plates 'T are secured to the'inclined portions of the sills 5 and extend across the car and haveflanged edges, which serve to stilen the web. Gross tie lateral braces 8and S connect the angles (Sand the web plates 7 respectively with theunder :traine of the car. in upright post 9 connectssithe web plete 7and the body bolster. Between these side trames, so formed, I arrangebuch "s l0 lo and will refer to them :and their rmneclions by the samereference numerals with Vthe addr tion of the exponent ait arecon'iposed oit' sheet metal, having truunions ll resting upon ,the sidoframes directly above the braces o so 'lhni the ioad willige transmittedthrough the truss trame and braces to the bolster, and each bucket iscomposed oi" sheet inetai formed with the lines of its joints allrunning towarffl the dumping end of the bucket, the lower por tion beingconstructed to drop down between the wheels, as will he set forth morein de tail in in v companion application hereuib` filed July l5), 190D,Serial'No. 508.494.

It will be understood thai ther-ar is pruvided with a bucket on nachside of iis transverse center, the buckets being simile. ly mounted andeach having :i lori-:ing device and a fluid pressure controlledmechanism for operating the same.

These buckets i The trunnions are so mounted on the Source of fluidpressure supply.

A vertically sliding bar movement, whenl furtherupward movement 15 ais provided on each side of the car having of thepiston head will tilt the buckets to 15 lugs 16 thereon, which areadapted to drop discharge their contents. lVith this appa- 30 downoutside the free ends of the locking ratus, therefo1e,the intialmovement ot' the latches and hold. them in their vertical or piston headwill trip the locking device to A locking position.
